I have a high-pressure AC line in the 97 Riviera that's leaking refrigerant at the valve fitting threads. Here's a diagram of the system from a local dealer with the area highlighted:
Since the tube assembly is NLA (no longer available) I'll need to find a replacement such as NOS (new-old-stock) or from a boneyard.
Here are pics of the leaking fitting.
Could the existing line be repaired? by an automotive or AC company?
